Collectors 17.62ct untreated sea green Aquamarine

This is a great collectors piece. It shows a strong sea green hue with fully open color, and eye catching internal characteristics that give it the illusion of seawater. It has a wide faceted top that takes full advantage its beautifully polished luster that twinkles across its face. It measures 17.8mm x 17.2mm x 8.8mm and was sourced from Brazil. Untreated!!!
